Description

METHOD FOR ROUTING DIGITAL MULTIMEDIA CONTENT IN REAL TIME USING AN ADDRESSING FUNCTION AND TRANSLATION EQUIPMENT

Field of invention

The field of the invention is that of methods for conveying digital content within a data network to a community of users. More specifically, the field of the invention relates to methods and systems for delivering simultaneous interpretation of digital content to a plurality of users in a plurality of languages. The field of the invention relates to methods comprising software means for processing dynamic routing of multimedia data according to a predefined user configuration.

State of the art

There are different techniques for delivering multimedia content corresponding to an oral translation or an interpretation of original content depending on the language of the user.

Among the existing solutions, there is a first family of techniques aimed at producing an automatic translation of digital content according to a translation engine. According to these latter techniques, algorithms using dictionaries, ontologies and thesaurus can be used to perform automatic translations. Artificial intelligences can be configured so that learning improves the fidelity of automatic linguistic translations. However, these techniques are not satisfactory both from the point of view of the quality of the automatic translation produced and from the point of view of the limitations encountered in generating multilingual translations for a plurality of users simultaneously.

Among the existing solutions, there is a second family of techniques aimed at the oral translation or the interpretation by one or more human translators, such as simultaneous interpreters, of an audio content and for which the data stream corresponding to the translated data is routed to the listener(s). These techniques generally involve an interpretation booth in which an interpreter receives an incoming audio stream and simultaneously produces an outgoing audio stream corresponding to the linguistic translation of the incoming content according to the determined language of translation. When different audio sources of different languages are produced, for example during a debate with different speakers speaking different languages, there is a real difficulty in simultaneously producing translated content for different users who have chosen different listening languages. Current techniques do not make it possible to configure a large number of listeners choosing their listening language in a configuration in which a plurality of speakers can produce content in different languages.

A difficulty comes from the fact that the configuration is difficult to implement from the point of view of the routing of digital audio content according to the person who speaks, the interpreters requested and the routing of translated content. Current solutions have the following main drawbacks: a complexity of the routing configuration to be implemented according to the operational configuration of the languages of the speakers, the listening languages and the translators and the translation latencies introduced by the complexity of the systems routing audio content.

There is a need to overcome the aforementioned drawbacks.

According to a first aspect, the invention relates to a method for routing multimedia digital content in real time comprising:

• Access by a first user to a digital service hosted on at least one data server from a first user terminal, said access comprising the selection of a first user language;
  • A first transmission of at least a first multimedia content by an addressing function to a first set of translation equipment to generate at least a second multimedia content corresponding to a first translation of said first multimedia content into the first user language, each translation equipment being associated with an input language and an output language and producing an activation signal or not indicating the generation of a second multimedia content;
  • an addressing function detecting the presence or absence of each activation signal from each of the translation devices;
  • A second transmission of the first multimedia content by the addressing function to the first user terminal when an activation signal is detected from a first translation device when the input language of said device is the first user language;
  • A third transmission of the second multimedia content by the addressing function to the first user terminal when an activation signal is detected from the first translation equipment whose output language is the first user language.

One advantage is to allow streams to be addressed almost instantaneously due to the detection of a signal emitted from translation equipment. One advantage of the solution is in particular to benefit from an analysis of the booths in order to deduce the languages of the speakers.

According to one embodiment, the detection of the presence or the absence of each activation signal by the addressing function makes it possible to determine a first value of the first multimedia content, said first value corresponding to the identification of a language among a plurality of languages.

One advantage is that just knowing the configuration of the cabins is enough to know the languages of the flows to be routed.

According to one embodiment, the deterministic position of a microphone of a translation equipment determines the generation of an activation signal, said first value being calculated from the deterministic position of a microphone of each set of translation equipment.

According to one embodiment, the method includes automatic deactivation of translation equipment whose input language is not the language identified by the first value.

According to one embodiment, the addressing function comprises a reading in a memory of each first user language each associated with a terminal identifier, said identifiers being associated with a first user language during access to the service by a user, the routing of the first multimedia content or the routing of the second multimedia content being determined according to:

• of the first value and/or;
• of the output language of a translation device whose activation signal has been generated.

One advantage is to know the language configuration of each user connecting to the service in order to automatically send him the content whose language corresponds to his configuration.

According to one embodiment, the addressing function is implemented by a virtual switch implementing the WebRTC, SIP protocol or any other audio-visual-text communication protocol.

According to one embodiment, the method comprises recording the configurations of each translation equipment connected to the data network, each configuration of each translation equipment comprising an input language, an output language, an identifier of the equipment translation, said recording being performed by a software function called digital interpretation control. One advantage is that the language configurations of each translation equipment also make it possible to configure routes between the booths themselves to route all the flows to all of the inputs and outputs that can be routed between the booths themselves.

According to one embodiment, the method comprises association data of two translation equipments recorded in a memory by means of the digital interpretation control room, said association data making it possible to define a translation booth, each translation equipment of the same booth comprising a communication interface for receiving a graphical interface on a display, said graphical interface representing a value of a digital handover indicator transmitted by one of the translation equipments to the other translation equipment of the same cabin. One advantage is to make interpreter passages more fluid using translation booths without latency.

According to one embodiment, a second user transmits the first multimedia content using a microphone and communication equipment.

According to one embodiment, the first multimedia content is transferred by means of a physical interpretation control room receiving a plurality of multimedia contents coming from a plurality of second users and generating at the output of said physical interpretation control room the first content multimedia to a digital interpretation control room. An advantage is to use the invention in a context of multi-listener conferences involving the implementation of a physical control room.

According to one embodiment, when an activation signal is not generated by a given translation equipment, the method comprises a selection of a second multimedia content corresponding to an output language of another translation equipment having generated the activation signal, said selection being made by means of a multimedia stream controller of said given translation equipment.

According to one embodiment, the calculation of said first value is, moreover, a function of:

• the selection of at least one piece of equipment for translating a second multimedia content via the controller or;
• the presence or absence of an activation signal from at least one piece of equipment for translating a second multimedia content.

According to one embodiment, when a new user terminal requires access to the remote server, said method comprises a memory in which is recorded an identifier of said new terminal and a language selected via the new user terminal.

According to one embodiment, the microphone of the first user's terminal is controlled according to a broadcast configuration of the first transmission, the first transmission possibly being of the unidirectional or bidirectional conference type.

According to one embodiment, the method comprises a step for defining a new conference, a step for assigning a type of conference to said conference and a step for associating a set of second users with said conference, said second users having rights to transmit a first multimedia content.

According to another aspect, the invention relates to a system for routing multimedia digital content in real time comprising:

• A plurality of multimedia acquisition terminals of a plurality of users, each multimedia acquisition terminal being associated with a predefined language;
• A plurality of user terminals comprising an identifier and the choice of a predefined language;
• Network equipment and a data server configured to implement the method of the invention.

In the remainder of the description, an “interpreter” or an “oral translator” is designated interchangeably as a translator, an oral translator or an interpreter. Interpretation equipment or translation equipment is designated by the notation “CAB”. We will speak of “translation equipment” or “interpretation equipment” interchangeably.

Speakers

There represents an embodiment of the system of the invention in which a set of microphones MIC ₁ and MIC ₂ correspond to microphones of speakers U _A , U _B speaking respectively in a first language FR, in French, and in a second language EN , in English. Speakers are users such as onsite speakers or people attending remote meetings.

According to another embodiment, the users U _A , U _B are users such as people expressing themselves within a two-way network by means of electronic terminals such as a computer, a tablet, a smart telephone (“ Smartphone” in English) or any other equipment comprising a user interface and a communication interface allowing connection to a Net data network.

According to another embodiment, the FR and EN input streams are multimedia content of audio type, text type, or video type. Multimedia content can be encapsulated within data frames of a real-time data transfer protocol suitable for data exchange on a data network, for example the Internet.

The multimedia content delivered by a user equipment, such as the microphone MIC ₁ or MIC ₂ of a speaker U _A or U _B is noted FL, designating the term "FLOOR" commonly used to define the channel selected by default equipment audio emitting an audio stream to a network or a physical control room. In the context of the invention, the multimedia stream FL denotes both a multimedia stream transmitted by equipment such as a micro MIC ₁ , a stream from an electronic terminal such as a smartphone or a computer, or a stream of equipment centralizing different channels such as a physical control room collecting a plurality of audio channels and delivering an output stream.

In the example of the , the multimedia stream FL is transmitted through a data network NET which can be a local network to an infrastructure or an open network of the Internet type. The FL stream can be transmitted by means of any communication protocol making it possible to exchange data frames on a data network. Preferably, a so-called real-time protocol is implemented so that the data frames are transmitted with a minimum of latency.

Access to the service by an auditor

In the context of the invention, a user U ₁ wishing to access the service implemented thanks to the invention registers with an identification service, for example, supported by a network infrastructure comprising equipment such as a data server SERV ₁ . The server SERV ₁ comprises means such as a computer and a memory to enable a user to define at least an identifier and a listening language L ₁ . According to one implementation, the server SERV ₁ is the same server as the server hosting the addressing function and/or the digital interpretation control function.

A user U ₁ will a priori keep the listening language L ₁ throughout the service regardless of the speaker U _A , U _B and their respective speech language FR or EN on the . The invention makes it possible in particular to perform a switchover of the routings of the translated contents respectively of each speaker in a fluid and instantaneous manner.

Digital content

The listening language corresponds to the language in which the user U ₁ wishes to receive the multimedia content corresponding to a determined digital content.

The determined digital content can be for example when it is an audio content:

• a conference or a debate by one or more speaker(s) located in the same place and broadcast in real time;
• a conference or a debate by one or more speaker(s) located in different geographical locations and broadcast in real time;
• a lecture or debate by one or more speaker(s) recorded and broadcast on demand;
• a telephone conversation with a predefined person,
• a telephone conversation with a plurality of predefined people,
• etc

The invention also applies to a determined textual digital content or a video.

There represents a user's equipment T ₁ in the form of an electronic terminal designating more broadly a Smartphone, a personal computer, a tablet or any other equipment which makes it possible to establish a digital communication through a data network. The equipment is configured in such a way as to allow the reception of a digital stream denoted TR or FL. However, the invention is not limited to the configuration of a unidirectional flow, but can be applied so that the user U ₁ is also a supplier of a multimedia digital content. For example, the stream transmitted by the user U ₁ can be an audio stream, a text or a video or the combination of these latter contents.

Translation equipment oral or interpretation

The invention comprises means CAB for implementing the generation of a second translated multimedia content TR from a first initial multimedia stream FL. In the rest of the description, such a means is called CAB translation equipment. We note in general in the description, the stream produced by a speaker a first multimedia stream FL or a first multimedia content and the stream produced by a translation equipment CAB a second multimedia stream TR or TR _L1 or a second multimedia content TR or TR _L1 . The notation TR is used to designate the second multimedia stream in the general case and the notation TR _L1 is used to designate the second multimedia stream in the case where the language L ₁ is also designated.

Each CAB translation equipment is associated with an input language L_Eand an output language L_S. Each CAB translation equipment produces an activation signal S_CABor not indicating the generation of multimedia content TR corresponding to the translation of an FL input multimedia content.

In its simplest configuration, the activation signal S _CAB is the multimedia content TR generated at the output of the equipment which is routed through the data network to an addressing function SW. In the latter case, a translation equipment CAB producing no output signal, therefore no translation, does not produce any activation signal S _CAB .

In other configurations, an activation signal S _CAB different from the multimedia content TR is produced, for example, from a distinct signal corresponding for example to the switching on of electronic equipment such as a microphone. According to another example, the activation signal S _CAB is generated from a metadata frame integrated into a message header encapsulating the digital encoding of the translated digital content TR.

The activation signal S _CAB is therefore generated each time a translation equipment CAB produces an output signal corresponding to a translation of an input signal. Thus, the activation signal can be generated each time an electronic equipment such as a microphone of the translation equipment is activated or each time a stream is produced.

These means can be, for example:

• a physical cabin in which a human translator receives, through a communication interface, an incoming audio stream and provides an outgoing audio stream rerouted within the NET network from a communication interface; the physical cabin can also be understood as a simple audio system making it possible to deliver sound to a loudspeaker and acquire sound via a microphone;
• an automatic translation machine comprising a software component configured to perform automatic audio translation from voice recognition software and instant translation software;
• a machine translation machine comprising a software component configured to perform textual machine translation from instant translation software.

Each CAB translation equipment can therefore be intended to operate automatically from software and hardware means or be intended to operate with a translator or an interpreter and a man-machine interface.

When a plurality of CAB translation equipment is configured within the framework of the invention, different embodiments can be implemented.

According to a first embodiment, the CAB translation equipment can be collocated in the same place. The latter can then include an interface with a physical RPI interpretation control room allowing the different flows of each equipment to be referenced according to the input and output languages of each equipment.

According to a second embodiment, each translation equipment CAB is directly connected to the data network NET by means of a communication interface. In this last embodiment, a digital RDI interpretation control room makes it possible to reference the different streams of each translation device according to the input languages L _E and output languages L _S of each of these devices.

According to a third embodiment, a first set of CAB translation equipment is directly connected to the data network NET and a second set of CAB translation equipment is co-located together within the same geographical location, each equipment CAB translation unit of this second set comprising a physical interface with a physical interpretation control room RPI in order to reference the different streams of each CAB translation equipment co-located within the same place. In this third embodiment, the physical interpretation control room RPI exchanges data with the digital interpretation control room RDI so that the digital interpretation control room RDI references all of the translation equipment CAB.

Addressing function

The invention includes the implementation of an addressing function SW. This last function SW can be implemented by any type of machine such as a data server, or a function distributed and implemented by a plurality of machines. In the example of the , a server denoted SW ₁ is configured so as to implement the addressing function SW and also the function of digital interpretation control RDI.

The addressing function SW is configured to carry out a transmission of at least one first multimedia content FL to a first set of translation equipment CAB to generate at least one second multimedia content TR _L1 corresponding to a first translation of said first multimedia content FL in the first user language L ₁ . The addressing function SW in combination with the digital interpretation control room RDI automatically routes the translated content TR to the equipment of the first user U ₁ whose language L ₁ is recorded in a memory and known to the addressing function SW during its implementation.

The addressing function SW is configured to detect the presence or absence of each activation signal S _CAB from each of the translation equipment CAB in order to initiate actions for conveying translated content TR to users who have chosen a language Output L _S corresponding to the language of the translated content.

To this end, the addressing function SW is configured to detect the presence of an activation signal S _CAB emitted by each translation equipment CAB. When the activation function SW detects an outgoing flow from a first translation equipment CAB ₁ by the presence of an activation signal S _CAB , a computer is configured to determine the input language L _E of the equipment CAB ₁ translation from the RDI digital interpretation control room. Indeed, the RDI digital interpretation control room is aware of each CAB translation equipment connected to the NET network and of its translation configuration which includes in particular the definition of an input language L _E and an output language L _S . The detection of an activation signal S _CAB makes it possible to know what is the input language L _E of the first active translation equipment CAB ₁ and therefore the language of the multimedia stream FL transmitted by a user U _A or U _B .

The method of the invention therefore makes it possible to convey:

• the outgoing flow TR to the users who have chosen a listening language L ₁ corresponding to the output language L _S of the active translation equipment CAB ₁ ;
• the flow sent FL to the users who have chosen the input language L _E of the active translation equipment CAB ₁ ;
• the outgoing stream TR from the first active equipment CAB ₁ to at least one other translation equipment CAB ₂ whose input language L _E corresponds to the output language L _S of the first active translation equipment CAB ₁ .

There illustrates an embodiment in which different equipment CAB1, CAB2, CAB3, CAB4, CAB5 are represented. Functionally, the set of translation equipment is denoted {CABi}, each CAB equipment being connected to the data network NET from any network access point.

Thus, the user U _FR who has chosen a FR language receives:

• be directly the flow FL when a speaker U_ATactivates his microphone MIC₁ and produces a flow in the language FR identical to that of the user U_FR. In the latter case, the addressing function SW by detecting the active translation equipment CAB3 due to the fact that a content TR is transmitted by the latter deduces that the input language L_Eof this CAB3 equipment is the FR language thanks to the RDI digital interpretation agency, which knows the configuration of the {CAB} translation equipment;
• or the stream TR _FR generated by the translation equipment CAB ₁ which corresponds to a translation of the first multimedia content FL coming from the microphone MIC ₂ of a speaker producing a first multimedia content in the GB language. In the latter case, the addressing function SW, by detecting the activity of the translation equipment CAB ₃ which is active because a content TR is transmitted by the latter, deduces that the input language L _E of this CAB3 equipment is the FR language. This deduction is also carried out thanks to the RDI digital interpretation control room, which has knowledge of the configuration of the {CAB} translation equipment.

Thus, for each user U _FR and U _EN , the two flows FL and TR _FR for the user U _FR and respectively FL and TR _EN for the user U _EN are represented on the , although these flows are not received simultaneously, but according to a sequence depending on the language of the speaker U _A or U _B .

There illustrates the case where a user U _CN having a terminal T3 and having configured a listening language CN when accessing the service from the server SERV ₁ receives a stream TRCN from a translation equipment CAB5. In this case, there is no translation equipment configured with an input language FR and an output language CN. The invention makes it possible to automatically route, thanks to the addressing function SW, either the content produced by the translation equipment CAB5 when the speaker transmits a multimedia stream FL in the GB language or the stream produced by the translation equipment CAB5 receiving the translated stream from the equipment CAB3 itself receiving the stream from the first speaker UA when the language of the speaker and corresponding to the content FL is the language FR.

The “iBP digital system” is called the digital platform and the equipment allowing the implementation in particular of the addressing function and the functions allowing the use of the method of the invention for a plurality of users. The addressing module is a software brick allowing the implementation of the addressing function.

The addressing function inherent in the system also allows the redistribution of multiple streams in a multiplicity of cases:

1/ In a first case, it allows interconnection with physical platforms. In this first case, the SW addressing function interconnects the digital platform with a physical interpretation platform through a single PC connected to the net. In this PC, a stream addressing module allows the interconnection of the iBP digital system with an external physical system, through an external sound card and a virtual sound card installed in this PC. This virtual sound card addresses the different digital channels conveyed by the stream addressing module on the different ports of the external sound card. Each of the streams is addressed in both directions: input and output.

2/ In a second case, the flow addressing module of the IBP platform allows the interconnection of flows from other digital videoconferencing platforms.

3/ In a third case, the incoming stream addressing module, also called "Switcher", makes it possible, from a single sound source, to distribute the stream to all the CAB cabins and all the users, by the through a single PC connected to the sound system of the room and to the Net.

4/ In a fourth case, the central system sends the information of all the flows corresponding to a multiplicity of conferences of the same event, on a terminal. This addressing allows the choice of the stream by room, by day and by language, as well as its deferred listening.

Thus, the invention allows a great capacity for configuration according to the language of the speakers and the languages chosen by users wishing to access the service.

There represents an embodiment in which the addressing function SW directly routes the first multimedia stream FL produced by a speaker to the terminal T ₁ of the user U ₁ . This routing of the first multimedia content FL is carried out following the non-detection of output streams from the translation equipment CAB ₁ to CABn.

In the case of the , the routing of the second multimedia stream TR to a terminal T ₁ of a user having chosen a language FR is determined by the addressing function thanks to the detection of a stream leaving the translation equipment CAB ₁ representing the activation signal S _{CAB 1} from the CAB1 equipment. The addressing function SW thanks to the digital interpretation control room RDI is aware that the translation equipment CAB1 is activated and that consequently the language of the first multimedia content FL is the language GB. This detection ensures:

• routing of the second multimedia stream TR _FR leaving the translation equipment CAB1 to the users who have chosen the FR language as well as to the translation equipment CABi configured with an input language L _E corresponding to the GB language and;

routing of the first FL multimedia content directly to users who have chosen the GB language.

FIGS. 3A and 3B illustrate that the outgoing flows of the other translation equipment CAB are cut off and that consequently the addressing function SW does not detect any activation signal S _CAB at the output of said translation equipment CAB. This detection also makes it possible to deduce that the input language L _E of each deactivated translation equipment CAB is not the language of the first multimedia content FL.

There illustrates a mode in which a new CAB ₂ translation device produces an outgoing stream in an FR language. The addressing function SW then determines the input language L _E of the translation equipment CAB2 corresponding to the language DE. The addressing function SW then engages the routing of the first multimedia content FL directly to all the users who have chosen the language DE and engages the routing of the outgoing stream from the translation equipment CAB2 to the equipment having chosen the language FR and possibly to CAB translation equipment having the FR language as input language.

There illustrates a case in which a translation equipment CAB ₁ configured with an input language L _E = FIN and with an output language L _S = DE whose TRDE output content is routed to the input of a translation equipment CAB2 configured with an input language L _E = DE and with an output language L _S = FR. The addressing function SW therefore makes it possible to automatically route the multimedia contents at the output of the translation equipment from the analysis of the active languages of the first multimedia content FL deduced from the deterministic states of each translation equipment CAB and according to the digital translation agency RDI who has knowledge of the configurations of CAB translation equipment.

Translation booth

The method of the invention also comprises software means for configuring translation booths formed of a plurality of CABi translation equipment each being configured with the same input language L _E and the same output language L _S . According to a preferred mode, a translation booth comprises two translation equipment items {CABi, CABk} configured with the same setting of input language L _E and output language L _S . An advantage of such a configuration is to make it possible to hand over from one translator to another translator after a certain time when the CAB translation equipment is intended to generate an audio multimedia stream from an audio multimedia stream entering a first language. The CAB translation equipment advantageously comprises a sound card, a loudspeaker and a microphone making it possible to offer the interfaces necessary for a translator to listen to and record audio multimedia streams.

Handover digital indicator

The invention makes it possible to implement a digital handover indicator IND _P between the two translation equipment {CABi, CABk} of the same cabin which is automatically generated following an action by one of the translators. An advantage is to generate a second multimedia stream TR corresponding to a translation of a first multimedia content FL over periods requiring a relay of translators passing hands in a fluid and continuous manner without deterioration of the quality of service in particular with regard to the transition period due to a change of translators.

The digital handover indicator IND _P allows a given translator in a booth to anticipate the continuation of a translation already started by a first translator. The second outgoing multimedia streams TR from the translation equipment CAB are naturally routed to the users thanks to the addressing function SW. Indeed, the new translation equipment CAB becoming active produces an activation signal S _CAB which makes it possible to route the second multimedia content at the output TR to users having the same language.

The digital handover indicator IND _P allows a signal to be routed between translators in the same booth so that the latter begin, for example, to produce a translation before switching on their microphone so that the transition has no consequence for the listeners.

The routing of the digital transfer indicator IND _P can be ensured, for example, by the addressing function SW and the digital interpretation control room RDI which is configured to know the configurations of translation equipment and therefore their association within cabins. According to another example, a digital handover indicator IND _P is transmitted by means of dedicated messaging between the translators of the same booth.

The digital handover indicator IND _P can take different values depending on which cabin translator generates it and depending on the status of the activation signal of the translation equipment CAB considered.

The translation equipment CAB can comprise a communication interface and a display making it possible to represent the different values of the digital transfer indicator IND _P . There represents an example of a generated graphic interface making it possible to restore the various values of the digital handover indicator IND _P of a translator of a cabin. The graphic interface can be generated from a calculator of a Smartphone, a tablet or a computer, or even from dedicated electronic equipment. In this example, it is assumed that the first translator is in the process of translating and generating a second outgoing multimedia stream TR and that the second translator takes over the current translation to replace the first translator.

A first value 11 makes it possible to inform the first translator of the booth that the second translator of the booth is ready to take over. A value makes it possible to inform on the contrary that the latter is not yet ready. This message is preferentially transmitted by the second translator from its interface. When the first translator perceives the active value 11 of the first indicator emitted by the second translator, it can engage the translation rocker by means of the change of value 10 of the digital transfer indicator IND _P . The second translator is then informed and begins to translate the audio content of the incoming stream FL to generate an outgoing stream TR.

According to one embodiment, the digital handover indicator IND _P is a composite indicator insofar as it makes it possible to exchange different values between the translators in a bidirectional manner.

According to one embodiment, the graphical interface offered within the CAB translation equipment of a second translator comprises a dual listening function which allows said second translator to listen to the first multimedia stream FL simultaneously with the stream of the first translator sharing the same cabin. This function can be engaged using a button type selector 20 that can be activated from the graphical interface. This function allows a better transition during the handover from the first to the second translator and therefore a better routing of the second multimedia stream TR transmitted to the user without degrading the transition time.
